与其关键元器件搭配使用，可用作单个电压基准、误差放大 器、电压钳位或具有集成基准的比较器。 TL43xx 能够运行并调整到 2.5V 至 36V 的阴极电压，这使得该器件成为了工业、汽车、电信和计算领域中各种终 端设备的最佳选择。若要将该器件用作并联稳压器或误差放大器，必须为阴极引脚提供 >1mA (Imin(max)) 的电 流。在这种情况下，可以从阴极引脚和基准引脚施加反馈，以创建内部基准电压的副本。 您可以购买初始容差为 0.5%、1% 和 2%（在 25°C 条件下）的各种基准电压选件。这些基准选件以在 TL431 或 TL432 之后跟 B (0.5%)、A (1.0%) 和空白 (2.0%) 的形式表示。TL431 和 TL432 的功能相同，但具有不同的引脚 排列选项。 TL43xxC 器件运行温度范围为 0°C 至 70°C，TL43xxI 器件运行温度范围为 –40°C 至 85°C，TL43xxQ 器件运行 温度范围为 –40°C 至 125°C。 8.2 功能方框图 CATHODE + REF _ Vref ANODE 图 8-1. 等效原理图 CATHODE 800 Ω 800 Ω 20 pF REF 150 Ω 3.28 kΩ 2.4 kΩ 7.2 kΩ 4 kΩ 10 kΩ 20 pF

2004 – REVISED MAY 2024 8.3 特性说明 TL43xx 由内部基准和根据基准引脚和虚拟内部引脚之间的差异输出灌电流的放大器组成。该灌电流由内部达林顿 对产生，如上文中的原理图（图 8-2）所示。使用达林顿对是为了使该器件能够吸收最高 100mA 的电流。 在具有足够电压余量 (≥2.5V) 和阴极电流 (IKA) 的情况下运行时，TL431 会将基准引脚电压强制为 2.5V。不过， 基准引脚不能悬空，因为基准引脚需要 IREF ≥ 4µA（请参阅电气特性，TL431C、TL432C）。这是因为基准引脚 会被驱动到 npn 中，后者要有基极电流才能正常工作。 当从阴极引脚和基准引脚施加反馈时，TL43xx 将作为齐纳二极管，根据向阴极提供的电流将输出电压调节至恒定 电压。这是由于内部放大器和基准进入了适当的运行区域。在开环、伺服或误差放大实现中，为了使该器件保持 在合适的线性区域，必须向其施加与在反馈情况下所需电流的大小相同的电流，从而使 TL43xx 具有足够的增益。 与许多线性稳压器不同的是，TL43xx 通过内部补偿来达到稳定，无需在阴极和阳极之间使用输出电容器。但是， 如果需要为该器件使用输出电容器，图 6-18 可作为一个指导，来帮助您选择用于保持稳定性的合适电容器。 8.4 器件功能模式 8.4.1 开环（比较器） 当 TL43xx 的阴极/输出电压或电流未以任何形式馈送回基准/输入引脚时，该器件便是处于开环状态。在向该器件 施加合适的阴极电流 (Ika) 后，TL43xx 将会具有 图 9-2 中所示的特性。这种配置具有如此高的增益，因此 TL43xx 通常用作比较器。TL43xx 具有集成的内部基准，因此，当用户想要监控单个信号的某个电平时，该器件 便成为了他们的理想选择。 8.4.2 闭环 当 TL43xx 的阴极/输出电压或电流以任何形式馈送回基准/输入引脚时，该器件便是处于闭环状态。涉及 TL43xx 的多数应用都是采用这种模式，从而实现调节至固定电压或电流的目的。反馈使得该器件能够作为误差放大器， 计算输出电压的一部分，并对其进行调整以保持期望的调节。实现该目标的途径是：将输出电压以某种方式关联 至基准引脚，从而使其等于内部基准电压（这可以通过电阻反馈或直接反馈来实现）。 Copyright © 2025 Texas Instruments Incorporated 提交文档反馈 23 Product Folder Links: TL431 TL432 English Data Sheet:

极电流 (IK) 时，TL43xx 将具有足够的开环增益来提供快速响应。图 9-2 展示了这种情况，其中 RSUP=10kΩ (IKA=500µA) 的情况要比 RSUP=1kΩ (IKA=5mA) 时的响应速度慢得多。在 Imin 附近及以下运行可能会导致增益较 低，从而导致响应速度缓慢。 9.2.1.2.1.1 过驱 未为基准引脚提供足够的过驱动电压也可能会导致响应较慢或不准确。该电压高于内部虚拟基准电压。内部虚拟 基准电压将在 2.5V ± 0.5%、1.0% 或 1.5%（具体取决于所使用的版本）范围内。所提供的过驱动电压越高， TL431 的响应速度就会越快。 对于 TL431 用作比较器的应用，最好是将跳闸点设置为高于正预期误差（对于 A 版本来说是 +1.0%）为了实现快 速响应，将跳闸点设置为高于内部 VREF 的 10% 就足够了。 为了实现从 Vin 到基准引脚的最低压降或电压差，建议使用阻值低于 10kΩ 的输入电阻器来提供 Iref。 Copyright © 2025 Texas Instruments Incorporated 提交文档反馈 25 Product Folder Links: TL431 TL432 English Data Sheet: SLVS543 TL431, TL432 www.ti.com.cn ZHCSJ14S – AUGUST 2004 – REVISED MAY 2024 9.2.1.2.2 输出电压和逻辑输入电平 为了使 TL431 能够正常地用作比较器，逻辑输出必须可供接收逻辑器件读取。这是通过了解输入高低电平阈值电 压电平（通常表示为 VIH 和 VIL）来实现的。 如图 9-2 中所示，TL431 在开环/比较器模式下的输出低电平电压大约为 2V，这通常已经足够支持 5V 的供应逻 辑。但却无法支持 3.3V 和 1.8V 的供应逻辑。为了适应这种情况，可以在输出端连接一个电阻分压器，以将输出 电压衰减到方便低电压逻辑接收器件读取的电压。 TL431 的输出高电压等于 VSUP，因为 TL431 处于集电极开路状态。如果 VSUP 远高于接收逻辑的最大输入电压容 差，则必须对输出进行衰减，以确保输出逻辑的稳定性。 当在输出端上使用电阻分压器时，务必要使电阻分压器（图 9-1 中的 R1 和 R2）之和远高于 RSUP ，以免影响 TL431 在关闭时将电压拉近至 VSUP 的能力。 9.2.1.2.2.1 输入电阻 在此应用中，TL431 需要具有输入电阻，以确保此器件所提供的所需基准拉电流 (IREF) 在开启期间保持在合适的 运行区域内。基准引脚上的实际电压为 VREF=VIN-IREF*RIN。IREF 可能会高达 4µA，因此建议使用足够小的电阻， 这将能够减小 IREF 通过 VIN 造成的误差。 9.2.1.3 应用曲线 5.5 5 4.5 4 Voltage (V) 3.5 3 2.5 2 1.5 1 Vin Vka(Rsup=10k:) Vka(Rsup=1k:) 0.5 0 -0.5 -0.001

阴极电流 基准初始精度 输出电容 9.2.2.2.1 可编程输出/阴极电压 为了将阴极电压编程至调节电压，必须对阴极和阳极引脚之间的电阻桥进行分流，即将中点处连接至基准引脚。 您可以在图 9-3 中看到该电路，其中电阻桥由 R1 和 R2 组成。您可以使用图 9-3 中所示的公式计算出并联稳压器 配置中的阴极/输出电压近似值。您还可以通过考虑阴极电流，更精确地确定阴极电压： Vo=(1+R1/R2)*VREF-IREF*R1 为了使该公式有效，TL43xx 必须完全偏置，以便它具有足够的开环增益来减小任何增益误差。这可以通过满足节 6.5 中指示的 Imin 规格来实现。 Copyright © 2025 Texas Instruments Incorporated 提交文档反馈 27 Product Folder Links: TL431 TL432 English

的精度 VI(dev) - 基准电压随温度的变化 ΔVREF / ΔVKA - 基准电压变化与阴极电压变化之比 |zKA| - 动态阻抗，通过阴极电流导致阴极电压的变化 将所有这些变量考虑在内，便可确定最坏情况下的阴极电压。应用手册 在可调并联稳压器上设置并联电压 (SLVA445) 可协助设计人员设置并联电压，以达到该设备的理想精度。 9.2.2.2.3 稳定性 虽然 TL43xx 在没有容性负载的情况下是稳定的，但是接收并联稳压器输出电压的器件可能会产生 TL43xx 稳定区 域（如图 6-16 和图 6-18 中所示）内的容性负载。此外，设计人员可以使用容性负载来改进瞬态响应或进行电源 去耦。在阴极和阳极之间使用额外电容时，请参阅图 6-16 和图 6-18。此外，应用手册 了解 TL431/TL432 数据表 中的稳定性边界条件图 (SLVA482) 可帮助用户更深入地了解此类器件的稳定性特征和选择合适的负载电容器。 9.2.2.2.4 启动时间 如图 9-4 中所示，TL43xx 具有高达约 2V 的快速响应，然后会缓慢充电至其编程值。这得益于 TL43xx 为了达到 稳定性标准而配备的补偿电容（如图 6-18 所示）。尽管存在二次延迟，TL43xx 的快速响应仍然能够满足许多钳 位应用的需要。 9.2.2.3 应用曲线 27 24 21

(2) Material type: When designated, preproduction parts are prototypes/experimental devices, and are not yet approved or released for full production. Testing and final process, including without limitation quality assurance, reliability performance testing, and/or process qualification, may not yet be complete, and this item is subject to further changes or possible discontinuation. If available for ordering, purchases will be subject to an additional waiver at checkout, and are intended for early internal evaluation purposes only. These items are sold without warranties of any kind. Addendum-Page 14 PACKAGE OPTION ADDENDUM www.ti.com (3) 29-May-2025 RoHS values: Yes, No, RoHS Exempt. See the TI RoHS Statement for additional information and value definition. (4) Lead finish/Ball material: Parts may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead finish/Ball material values may wrap to two lines if the finish value exceeds the maximum column width. (5) MSL rating/Peak reflow: The moisture sensitivity level ratings and peak solder (reflow) temperatures. In the event that a part has multiple moisture sensitivity ratings, only the lowest level per JEDEC standards is shown. Refer to the shipping label for the actual reflow temperature that will be used to mount the part to the printed circuit board. (6) Part marking: There may be an additional marking, which relates to the logo, the lot trace code information, or the environmental category of the part. Multiple part markings will be inside parentheses. Only one part marking contained in parentheses and separated by a "~" will appear on a part. If a line is indented then it is a continuation of the previous line and the two combined represent the entire part marking for that device.
